Question

Janine inflated a ball to a radius of 18 cm and another ball to a radius of 12 cm.

Answer 1

Answer:since your are looking for the volume of the ball, the answer would be 17182.08

Step-by-step explanation:

Answer 2

Volume of a ball = (4/3)πr³

When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
 Difference = 24416.64 - 7234.56 = 17182.08 cm³

the volume of air in the larger ball is 17182.08 cm³ greater than smaller ball
